2 GETTING STARTED / 2.4 System Structure70FUNC (E)/ Ver 2.00Synchronization between a Main Repeater and a Sub Repeater is restored when the network device is replaced andthe network connection between a Main Repeater and a Sub Repeater is restored. At this time, a Main Repeater migratesfrom Failsoft Mode to the Standby state. A Sub Repeater restores the Hot Standby behavior to maintain the Active state.Because a Main Repeater and a Sub Repeater are synchronized, if Auto Active Status Switch is configured, therepeater in the Active state is replaced according to the configuration. Or, the repeater in the Active state can be manuallyreplaced by Active Status Switch. In addition, the status of each repeater can be confirmed from Hot Standby Statusof the Web Tool and the OLED display.Repeater failure (Main Repeater)Status: Main Repeater (Active)/ Sub Repeater (Standby)If a Main Repeater fails for any reason and is replaced, a Sub Repeater cannot synchronize with the Main Repeater. Inthis case, a Sub Repeater migrates to the Active state.Figure 2-10 Repeater (Main) FailureRepeater (Main Repeater) recovery precautionsRemove the failed Main Repeater and perform the recovery procedure.The configuration of a Main Repeater to be replaced needs be the same as the one prior to replacement, and Writeneeds to be performed beforehand.
